We already know that a WiFi-only Nook is on the way and it appears to have hit Barnes & Noble's inventory system. Apparently, this could be hitting their stores this Wednesday for $149, so we'll really just have to wait and see. It's less than 3 days away if you're waiting for it though.

Update: A newer post from Engadget has pointed out that there is actually a new listing for the WiFi Nook at Best Buy (here). It's obviously going for $149.99, and you can pre-order it now if you'd like. When it will ship is beyond me, so maybe it's on track for a Wednesday release.

Update: It's now official. Barnes & Noble has just announced it here. They have said that's now available to order on Bestbuy.com and Nook.com. B&N has also decided to cut the price of their 3G model to $199.99.
